These calls can require an access share lock on the table, which might conflict with an existing or later acquires lock. So perform these calls while we already have an exclusive lock on the table. This unfortuantely means that we ave to remove the constness of the table parameter to repack_one_table, as it is not modifying the table object to set up the indexes.

WARNING: the table "trg2" already has a trigger called "z_repack_trigger"
|
|
DETAIL: The trigger was probably installed during a previous attempt to run pg_repack on the table which was interrupted and for some reason failed to clean up the temporary objects. Please drop the trigger or drop and recreate the pg_repack extension altogether to remove all the temporary objects left over.

WARNING: trigger "z_repack_trigges" conflicting on table "trg3"
|
|
DETAIL: The trigger "z_repack_trigger" must be the last of the BEFORE triggers to fire on the table (triggers fire in alphabetical order). Please rename the trigger so that it sorts before "z_repack_trigger": you can use "ALTER TRIGGER z_repack_trigges ON trg3 RENAME TO newname".
